1 Claim. (01. 21541) This invention relates to improvements in nonrefillable valves for bottles, one object of the invention being the provision of a valve having a ball that is protected against tampering with through the outlet end thereof, so that a practical and relative inexpensive device for this purpose is provided for use against spurious filling of the bottle after the same is empty.

Another object of the present invention is the provision of a non-refillable single ball valve that fits cork tight within the neck of a bottle sufliciently far below the outlet'of the neck to permit the usual sealing devices now employed, and which unit cannot be removed through the outlet of the neck without damages thereto that would indicate that the same had been tampered with.

In order that the invention may be fully understood, attention is invited to the accompanying drawings, in which:

Figure 1 is a vertical central section through the valve made in accordance with this invention, as mounted in the bottle neck and in an upright position.

Figure 2 is a similar view with the valve in fluid releasing position.

Figure 3 is a top plan view of the valve per se.

Figure 4 is a side View of the valve per se.

Figure 5 is a view showing the internal parts in elevation with the casing in section.

Figure 6 is a bottom plan view of the internal parts alone without the carrying casing.

Figure '7 is a plan view of thevalve-seat disk.

Figure 8 is a view similar to Fig. 4, showing the upper portion in section and provided with a supplemental guard.

Figure 9 is a view showing such guard.

Referring to the drawings, the numeral I designates a main casing of the valve, made of a plastic and molded or cast to provide an inner ball guide or hollow stem 2 in the form of a cylindrical skirt, and being provided upon its lower end with a plurality of outlet openings 3. Providing a guard or cover for this skirt and integral with the upper edge thereof is a dome 4, the latter with the stem 2 constituting a mushroom-shaped member--and the outer rim 5 extends beyond the skirt 2 and is integral with the inner portion at 6 of the casing I. The portion of the dome above the annular chamber 8, formed between the skirt and casing I, is provided with outlet openings 1, which are staggered as relates to the respective openings 3, see Fig. 6. This is for the purpose of rendering it impossible for a tool or wire being inserted through one of the.

openings 1 to pass through an opening 3 to hold the ball 9 01f its valve seat II of the closure disk Ill, which is secured non-leakable to the lower edge of the casing I.

The ball 9 is slidable within the skirt or stem 2, being slightly less in diameter than the diameter of suchstem or skirt, so that when the bottle is moved from the position of Fig. 1 to that of Fig. 2, the ball will roll to leave the valve seat and thus permit liquid to fiow through the valve seat opening, the openings 3 on the lower side of the unit, into the chamber 8, and through the openings i at the lower side'of the dome and out of the bottle neck I2. Also when the bottle is decanted to about or less than two-thirds full, the openings 1-3 at the upper side of the valve, permit air to enter the bottle and thus the liquid flows more-freely from the neck of the bottle.

In assembling, the parts I, 2 and 4 being integral, the ball is inserted into the skirt, and the disk Ill is then heat sealed, or may be attached by screw threads.

In valves of this type, its cost must be para mount, that is they must cost the least possible amount, and as plastics are now at hand, by means of which a cork-tight joint between the inner wall of the neck of the bottle and the valve is now possible, the main parts of the same can be molded integral, so that the cost of assembly is reduced, and the valve itself can be easily put in place by the automatic machinery now in vogue in bottle filling and capping establishments. Also inasmuch as a plastic is used in the present instance, the main casing i, the stem 2 and the dome t are made integrally, so that the ball 9 is readily inserted into the stem 2, and the casingv and stem then closed by the valve port carrying member id.

It is also intended that the plastic such as poly ethylene used in this unit and particularly the casing I, is of the tough yet compressible type, so that it has a non-leak fit as a cork in the neck of the bottle, when forced therein after the bottle has been filled. It may, however, be attached by an aluminum ring to the top of the neck of the bottle, or otherwise attached.

In Figs. 8 and 9, the casing is is provided with a supplemental guard I l, which in turn is pr vided with segmental openings I5, to permit free flow of the liquid during decanting. This is an added barrier against tampering with the ball 9.

What is claimed, is:

A non-refillable valve to fit liquid tight as a cork within the neck of a bottle, comprising a tubular molded plastic casing and constituting a cork element, a mushroom-shaped member having apertures adjacent its rim and having its rim integral with the casing and its dome below the outer end of the casing, the stem thereof 3 being a hollow valve guiding tube close at one end by the dome and integral therewith, and having egress ports adjacent its free end, said stem providing an annular chamber between it and the adjacent part of the wall of the casing so that the egress ports provide communication with the annular chamber and the apertures of the dome provide outlets for the annular chamber, a valve ported closure for the lower end of the casing and stem, said casing, the mushroomshaped member and the valve ported member being made of polyethylene, and a ball mounted for rolling movements within the stem to and from the port of the valve ported closure.
